Does the GCS22U have a "HOT KEY" function?
Thank you for your inquiry. We did not find any reference to Hot Key switching functionality in the documentation. The manual only references the push button.

Can I switch between computers using keyboard in case the wired remote switch button cut off
Thank you for your inquiry. Unfortunately, it looks like this KVM does not support hotkey switching via the keyboard. Switching can only be accomplished by the push button on the remote controller.
